Inside the mind of an online troll

Armies and armies of trolls wreak havoc on the internet, but we never see any of them. We don't know who they are, but we encounter them everywhere on a daily basis.

In this episode of GMA News Online's Stand For Truth, Darwin Quirino asks a sociologist why internet trolls are so effective in provoking and influencing the online community.

Or you can take it from a troll himself.

Self-confessed army troll "Echo" walked us through the craft of using fake accounts to stir up public discourse. He also revealed how they can spread false information in favor of their "clients" during the elections.

The National Bureau of Investigation (NBI) Cybercrime Division, on the other hand, explains why they have yet to be successful in going after trolls, including those who have already been identified.
